Copy Move Files - PHP
A simple example of imitating elFinder and extracting key member methods
The implemented functions are:
Realize multi-file copy or move operations
Note: In order to facilitate testing, some judgments have been simplified. And a new test folder will be generated as the destination folder in the directory where the program file is located. Modification is required if actual use is required.
